I have some geometry edges and at each vertex that's linked to two edges I want an instance of an object and I want these instances to be oriented between the edges. On the left is an example of the desired result and on the right is where I'm stuck:
In theory I should get two adjusting vectors for each point, find their dot product and then arccos the result. In practice I guess something in my tree isn't doing that.
My GN tree:
and my scene:
